Marine Research Student Colloquium

Marine Research Student Colloquium CANCELLED

11 Jan 2021

Dear College of Charleston Community,

We regret to announce that the Marine Graduate Student Colloquium Committee has unanimously voted to cancel the Colloquium at Patriots Point for Spring 2021 (rescheduled from Fall 2020). The recent rise in coronavirus cases, increase in percent positivity, and predicted surge in coronavirus cases are not conducive to safely gathering off-campus. 

Be safe,
Drs. Heather Spalding and Dan McGlinn
Co-Chairs
Colloquium Committee

Saturday, February 27, 2021 at Patriots Point Naval & Maritime Museum

Virtual Keynote Speaker

Brian Bowen, Research Professor
Hawai'i Institute of Marine Biology, University of Hawai'i at Mānoa

 

MARINE CONSERVATION GENETICS
from ancient mariners to future biodiversity 

The presentation covers the application of genetics to marine conservation in three 20-minute modules. Part 1 uses the Orlog metaphor from Norse mythology to examine the multiple roles that genetics plays in marine conservation, with examples from the Hawaiian Archipelago. Conservation programs must protect the threads of life as the arrive from the past (phylogenetics), thrive in the present (ecology) and project into the future (evolution). These three goals are embodied by the Norn sisters of Norse mythology, whose names correspond to past, present, and future. The phylogenetic and ecological goals are firmly embedded in conservation, but preserving the materials for future biodiversity is a new and exciting frontier.

Part 2 is a case history on how genetics has reshaped the conservation of sea turtles. In one of the earliest applications of DNA data to conservation issues, mtDNA studies demonstrated that reproductive behavior in sea turtle is guided by natal homing. After a maturation period spanning decades and thousands of kms, sea turtles return to the vicinity of their natal beach to mate and nest, as indicated by strong (and sometimes diagnostic) shifts in haplotype frequencies between nesting colonies. Each nesting colony is an isolated management unit which will thrive or perish without input from other nesting colonies. In some cases, mtDNA haplotypes serve as barcodes to indicate the natal origin of turtles impacted by fisheries and other human activities.

Part 3 is focused on future evolutionary diversity, in particular the origins of tropical marine biodiversity. The Coral Triangle between Indonesia, Philippines, and New Guinea hosts the highest marine biodiversity on the planet, including >75% of worldwide coral diversity and >35% of reef fish diversity. Phylogenetic studies reveal that more than half of the reef fishes in the Indo-Pacific have origins in the Coral Triangle biodiversity hotspot. On the edges of the Indo-Pacific, peripheral habitats including Hawaii and the Red Sea have much lower diversity, but high levels of endemism (species found nowhere else). It was long assumed that these endemism hotspots were evolutionary dead-ends that received species via colonization, but did not export new species. However, recent phylogeographic studies have demonstrated that these endemism hotspots can both receive species from biodiversity hotspots, and export new species, in a process labelled biodiversity feedback.
